Following a volcanic eruption in Ethiopia, ash clouds have formed and drifted into various regions, including parts of India, raising significant concerns for flight safety. The Directorate General of Civil Aviation (DGCA) in India has released an urgent warning for all Indian airlines, advising them to steer clear of regions impacted by volcanic ash at potentially dangerous altitudes to protect passengers.

The Hayli Gubbi volcano in Ethiopia erupted on November 23, 2025, after being dormant for over 10,000 years, sending thick smoke and ash plumes soaring up to 14 kilometers into the atmosphere. These clouds have already reached Yemen, Oman, and northern, eastern, and northeastern parts of India, with further drifting expected in the coming days.

Volcanic ash poses serious dangers for aviation, as it comprises abrasive particles that can lead to engine damage and failures, alongside affecting other aircraft components and sensors. In reaction to this hazard, the DGCA has mandated airlines to revise their flight plans and fuel calculations, and to report any suspected ash encounters including unusual engine performance or cabin anomalies.

Several flights have been directly impacted by the ash clouds; an example includes an IndiGo flight diverted from Kannur to Ahmedabad, along with cancellations in other affected areas.

To safeguard passengers and aircraft, the DGCA requires airlines to perform extensive inspections on both engines and aircraft structures following flights in proximity to ash-affected zones. Furthermore, operations at airports confronted with ash risks may face suspension or delays should conditions deteriorate. Flight dispatchers will aid in continuously monitoring ash advisories, satellite imagery, weather reports, and ash trajectory forecasts for timely updates.

Airports experiencing ash contamination are also mandated to inspect and cleanse runways, taxiways, and aprons prior to resuming regular activities. In instances of severe ash deposits, airport operations may be restricted or temporarily halted to avert any risks or damages.

The DGCA’s advisory is consistent with guidance from the International Civil Aviation Organization (ICAO), stressing adherence to safety protocols and manufacturer recommendations to protect the aviation sector through this natural occurrence.

This volcanic ash event underscores the necessity for heightened vigilance and collaboration among aviation authorities, airlines, and airports, ensuring effective management of volcanic risks and the safety of air travel across affected areas.
